Final answer:
A project manager is the most likely to be good with early start, early finish, late start, late finish, slack, and critical path.
Step-by-step explanation:
When it comes to understanding early start, early finish, late start, late finish, slack, and critical path, a project manager would be the most knowledgeable. These terms are commonly used in project management to schedule and organize tasks in order to complete a project efficiently and on time. For example, a project manager would use these concepts to determine the earliest and latest possible start and finish times for each task, identify the critical path (the longest sequence of dependent tasks), and calculate slack (the amount of time a task can be delayed without affecting the overall project timeline).
